What is Brown Noise?
Brown noise (also called Brownian noise or red noise) is a type of signal noise with a power spectral density that decreases by 6 dB per octave. This gives it a deep, rumbling quality similar to a strong wind, a river, or distant thunder. The name comes from Robert Brown, who discovered Brownian motion, not the color.

Frequently Asked Questions
Is brown noise better for sleep than white noise?
Many people find brown noise more soothing for sleep because its deeper, lower frequencies are less harsh than white noise. The rumbling quality can feel more natural and relaxing. However, personal preference varies, so try both to see what works best for you.
Can brown noise help with ADHD?
Some research suggests that continuous noise like brown noise can help people with ADHD focus by providing consistent auditory stimulation that reduces distractibility. Many people with ADHD report that it helps them concentrate, though it's not a substitute for professional treatment.
Why is it called brown noise?
Brown noise is named after Robert Brown, the Scottish botanist who discovered Brownian motion - the random movement of particles in a fluid. The noise follows this same random-walk pattern mathematically. It's not related to the color brown.
